JSP vs Python any takers

[TC]

Hi ALL

1) If you have python script does the python interpreter have to recompile
the code  every time
    it is executed from a WEB page, can it be compile once like java can on
a JSP page

2) On a linux apache box is there a python add-in that allows phython script
to be used to create
   dynamic pages like you can when you use python script on an M$ IIS web
server

3) Pound for pound how does  a JSP app scale vs a python WEB app

why would I use python over JSP
